IRONINGBOARD.

To @ZZ whom it may concern Be it known that I, VILLIAM B. Trina MAN, acitizen of the United States, residing` at Madera, in the county ofMadera and State of California7 have invented new and usefulImprovements in ironing-Boards, of which the following is aspecification.

The present invention relates to a means in combination with an ironingboard whereby the latter may be conveniently, quickly and substantiallyconnected and adjusted with relation to a table.

The object of the present invention is to provide a substantial butsimple clamp for ironing boards whereby the latter may be,

with great facility, rigidly and firmly connected to a table or othersupporting element.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure l is a sideelevation of the ironing board. Fig. 2 is an end view of Fig. l.

The present invention comprehends a support and clamp in combinationwith an ironing board, as 2, to the lower surface of which there isattached at a suitable distance from one end of the board a transversebearing 3. This bearing is channeled on its lower side as at 4 in thedirection of the length of the board 2 and is adapted to receive aportion of the lever 5 between the sides of the channel. A centrallylocated bolt 6 projects downwardly from the bearing 3 through the recessor channel portion 4, and passes loosely through an alined opening inthe lever 5 in such manner as to allow a limited rocking or universalmovement thereof. The shorter arm of the lever 5 projects forwardly fromthe bearing 3; the end of the arm being substantially even with the endof the board. The upper surface of the lever or clamp is spacedsufficiently from the lower surface of the board 2 to permit theinsertion between the two members of a shelf or table to which it may bede sired to temporarily attach the structure. The distance of theshorter end of the clamping lever 5 from the adjacent parallel end ofthe board may be determined by advancing or receding nuts 7 which are adjustable upon the post G depending from the bearing 3.

Serial No. 676,423.

When it is desired to clamp the board to j a table, the lever 5 isrocked about its support or post 6 by means of a cam lever or frame 8,pivoted at 9 adjacent to the end of the longer part of the lever 5, andprovided with a friction or cam surface 10 adapted to swing into bindingengagement with the lower surface of the ironing board 2 and thus forcethe operative or short end of the lever 5 into clamping contact with theledge or top of the table indicated at A. rlhe lower end of the frame 8,when so swung as to cause the lever 5 to clamp the table, rests on theiioor and serves as a support for the board. The cam lever 8 may beswung sufficiently about its pivot 9 on the lever 5 so as to spring thelever 5, thus producing ample friction or gri aping effect of theclamping end of the )lever 5 against the table top. I lock the thrustlever 8 in adjusted supporting position by using a locking rack bar llwhich is pivoted at l2 to the outer end of the ironing board; the bar 1lbeing provided with a number of notches 13, one of which may be adjustedover a pin 14 extending transversely through the strut or cam lever S.

By means of the great leverage of the member about its fulcrum 9, thecam l0 of the member 8 can be forced with great pres sure against theunderside of the ironing board, and this in turn exerts great force onthe outer or longer end of the lever 5 to bring its shorter clamping endagainst the underside of the table 2 with great force. By undercuttingor recessing, as at 1G, that end of the ironing board which overlies thetable A so as to form bearing surfaces 17 adjacent to the sides of theboard, and by locating the operative clamping face of the lever 5substantially midway between the bearing surfaces 17 of the board, thepressure of the clamping lever 5 will tend to draw the bearing surfaces17 with great friction against the top of the table and prevent relativemovement of the board and the table as long as the locking device 8 isswung so as to bear against the underside of the board 2.

It will be seen from the foregoing that the means for locking the boardin relation to a suitable support consists primarily of a resilientlever, as 5, of the first order, one end of which serves as a clamp whenpressed into engagement with the supporting member to which the board isto be temporarily attached; this pressinof of the lever 5 beingaccomplished by rocking it on its support, as the 0st G, by means of acam lever fulcrume on the end of the lever opposite to its clamping end.

lVhen the ironing board is not in use the locking lever 8 may be swungabout its pivot 9 on the clamp 5 until it is carried over a latch 15near the outer end of the board; the latch being adapted to be turnedover to engage a brace or transverse rod 1Ga adjacent to the free end ofthe lever S. This means of latching the frame 8 prevents it from fallingor swinging about when the device is out of use.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- In a device of the class described, a board, arecessed block secured to said board on the under side and near one endthereof, a bolt a limited universal movement, a cam leverv carried bysaidV lever and cooperating with `said board to support the same, and anindependently adjustable,` rack bar pivoted to the outer end of theboard andengageable with the cam lever to hold the parts-in adjustedposition. v

In testimony whereof I-have hereunto set `my hand in the presence of twosubscribing' witnesses.
